DESCRIPTION

The baudrate routine returns the output speed of the terminal. The
number returned is in bits per second, for example 9600, and is an
integer.

The erasechar routine returns the user’s current erase character.

The erasewchar routine stores the current erase character
in the location referenced by ch.
If no erase character has been defined, the routine fails
and the location referenced by ch is not changed.

The has_ic routine is true if the terminal has insert- and delete-
character capabilities.

The has_il routine is true if the terminal has insert- and delete-line
capabilities, or can simulate them using scrolling regions. This might
be used to determine if it would be appropriate to turn on physical
scrolling using scrollok.

The killchar routine returns the user’s current line kill character.

The killwchar routine stores the current line-kill character
in the location referenced by ch.
If no line-kill character has been defined,
the routine fails and the location referenced by ch is not changed.

The longname routine returns a pointer to a static area
containing a verbose description of the current terminal. The maximum
length of a verbose description is 128 characters. It is defined only
after the call to initscr or newterm. The area is
overwritten by each call to newterm and is not restored byset_term, so the value should be saved between calls tonewterm if longname is going to be used with multiple
terminals.

If a given terminal does not support a video attribute that an
application program is trying to use, curses may substitute a
different video attribute for it.
The termattrs and term_attrs functions
return a logical OR of all video attributes supported by the
terminal using A_ and WA_ constants respectively.
This information is useful when a curses program
needs complete control over the appearance of the screen.

The termname routine returns the terminal name used by setupterm.

RETURN VALUE

longname and termname return NULL on error.

Routines that return an integer return ERR upon failure and OK
(SVr4 only specifies "an integer value other than ERR") upon successful
completion.

NOTES

Note that termattrs may be a macro.

PORTABILITY

The XSI Curses standard, Issue 4 describes these functions. It changes the
return type of termattrs to the new type attr_t.
Most versions of curses truncate the result returned by termname to
14 characters.
